To all 'io/0m #may concern j Be it known that l, NaroLnoNBoNAPanrnALLEN, a citizen ot the United States, and a resident oit New Hyde Park,county of Nas- `sau,`State oitNew Yorlnhave invented certain new anduseful improvements; in j Hingestor Curtain Stretchers, of which thefollowing` a lull, clear, and exact description. l j `Among theprincipal objects which the present invention has in Viewy are: Toproduce a joint or" the character mentioned without increasing the bulkoi the joined members; to form `a rigid connection for C end-buttedcoextensive members; to effect the joint quickly; and `to simplify andcheapen the construction.

Draco/uga Figure l is a side view of a joint con structed and arrangedin accordance with the present invention, the parts being shown by fulllines in their closed or active relation and by dotted lines in theiropen or inactive relation; f

Figure 2 is a side View taken from the side of the members opposite tothat shown in the previous figure; j

Description.

The present invention is adapted for various employment but isparticularly adapted for use in conjunction with lace curtain stretchertrames, being there employed for connecting the sections of theelongated side members of the frame. It is in this con# nection theinvention is illustrated in the accompanying` drawings, wherein the twosections are indicated by the numerals 9 and 10. rl`hese sections arepreferably grooved at their inner edge to form the under-cut` edge 11,which is usually provided with nec-- essary pins for threading thecurtain upon.

As is well known, the elongated side members of the frame are preferablyformed from a plurality of sections which are either" separated andpacked for storage or hingeconnected so that they be released anddisposed for storage.

The hinge employed in the present invention consists principally of thehinge butts 14. The lugs are pivotally united by hinge pin 16, thecenter of which is disposed j in line with the ends of the linerbrackets 17 with which the said butts are each provided. The linerbrackets 17 serve to engage one edge oteach 'of the members 9 and 10 and12 and 13. The butts l2 and 13 'have hinge j knuckle lugs 14- and 15respectively. ris best seen in` Figure ot the drawings, the portion ofthe butt 13 bearing the lug 15is offset a distance equal to the'thickness et the lugs the true the disposition ot the butts 1.2 and 13thereon. This construction renders the operation ot settingthe butts onthe sections 9 and simply and easily accomplished, all that is necessarybeing to `rest the overturned endsof the brackets 17 on the edge of thesaid sections beforev the `fastening` screws 18 `are driven.

It will be noted that the butt '13 and the portion thereof carrying thelug overlaps the end of the butt 12 with the result that the partingedges of the joined butts are on a plane otlset from the planecoincidentwith the center of the pin 16. This is best shown in Figure 1 of thedrawings. This arrangement allows the latch 19 to draw the ends otA thesections 9 and 10 more rigidly together in the portions thereofjuxtaposed to the pin 16.

The latch 19 is pivoted by means of the pin 2O to the over-hangingabutment 21 on the butt 13. lWhen the latch is swung to the positionshown in Figures 1 to 3 the body of the latch extends under the'abutment22, The latch 19 has an 11p-raisedfoot 23., that is formed to bearagainst and to ride over the wedging edge 24 of the abutment 22. This isshown best in Figures 1 and 3 ot the drawings.

Due to the inclined surface of the edge of the abutment 22 the latch 19is permitted to exert a wedging pressure on the abutment 22 to force thesame against the abutment 21. i

The latch 19 is preferably provided with a handle 25 by whichthe saidlatch may be swung to the active and the inactive positions thereofdisclosedin the drawings.

It is obvious that the butts 12 and 13 are so simple of form andconstruction as to` admit of being stamped or otherwise quickly producedfrom light or cast metal. It is also obvious that the hand work incidentto the construction of the hinge joints being j the sections 9 and l()or parallel Withthe aXis of the hinge pin 16. A simple, inexpensive andrigid hinge joint is thus produced.

Claims .I

1.An article as characterized comprisingy a plurality of hinge butt-spivotally connected at approximately the termination of vthe meetingedges of said butts and having l abutment members adjacent the oppositeextremity of said meeting edges, said abutment membersbeing extendedfrom said butts in approximately perpendicular rela-k tion thereto; alatch pivotally mounted on one 'of said abutments for engaging the otherof said abutments to draw said abutments together; and ak plurality ofliner brackets eX- v tending trom the edge of said butts insubstantially perpendicular relation thereto,

' said liner brackets being relatively disposed v the foot 23 and theedgey 94 ofthe butt 22 and by the portion thereof' which isperpendicular to the long axis of,

in lines perpendicular to the meeting edges of said butts. v

2. An article as characterized comprising a plurality of elongated ia'tthin hinge butts the meeting portions whereof over-lap to -form hingelugs extending below the body of said butts; a plurality of abutmentbrackets integrally fomned on said butts adjacent the meeting' edgesthereof `and eX- tended therefrom' in substantially perpendicularrelation (thereto,I the edge of one of said abutment brackets beinginclined from the outer edge toward the body of the butt with which itis connected; a plurality of liner brackets integrally formed on saidbutts and extended therefrom to a plane parallel with the center ofsaidv butts and perpendicular to the meeting edges thereof. said linerbrackets being bent to a plane co- 'extensive in allvof said bracketsand perpendicular tothe plane of said butts;` and a latch connected toone of said abutment brackets to swing Between the said abutment bracketand` the article With which said butt is associated. said latch havingan upset head integrally formed Withsaid latch for engaging the otheroit' said brackets to ride over the inclined ed e thereof.
